GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 404,508, dated June 4, 1889.

A plication filed January 14, 1884- Serial No. 117,441. (No model.)

To all whom, it may concern:

Be it known that I, OLE O. STORLE, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Grain -Binders, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of the cordholding, knotting, cutting, stripping, and tucking devices as setn from the stubble side of a self-binding harvester. Fig. 2 is a front view of the same parts. Fig. 3 shows the same parts as Fig. 2 as seen from beneath. Fig. 4 shows the cam and gear wheel for giving motion to all of the moving parts enumerated above. Fig. 5 is a perspective view of the knotter-frame. Fig. 6 is a side view of the segmental cam and gear wheel in sec tion. Fig. 7 is a sectional view of the segmental cam and gear wheel, the disk of the same being removed to show the tucker and the contour of the cam-groove for moving it.

Fig. 8 is a front view of the parts shown in' Fig. 7. Fig. 9 is a perspective view of the tucker. Fig. 10 shows the tucker in position for acting as a stop to retain the twine in position on the knotter. Fig. 11 shows the position of the tucker-finger after having delivered the twine to the knotter.

The object of my invention is to perfect the band-uniting mechanism, and its nature will be hereinafter fully point-ed out.

My devices, as shown, are adapted to the form of binder having a frame shaped like the letter U on its side, in the arms of which are bearings for the knotter-driving shaft and needle-shaft, as shown in various patents.

, 1n the drawings,A is the knotter-driving shaft, having keyed to it on either side of the knotting mechanism the discharge-arms A A Keyed to this shaft is the miter-gear A Supported loosely on this shaft, so as not to be revolved by it, is the knotter-frame B. (Shown in perspective in Fig. 5, where B is a sleeve which forms a bearing on the shaft A.)

B is an arm thrown out to assist in supporting the breast-plate.

B are holes through which screws pass to secure the knot-ter-shaft bearingto the frame.

15 is a stud 011 which the cord-holding disk is supported and revolves.

B is a sleeve in which the shaft of the tucker rocks. 7

1-3 is a recess formed by the casing B in which the miter-gear L on the segmental shaft is slotted through to receive the movable jaw, so that the point F of the pivoted jaw of the knotter will bear against the end of the fixed jaw. The movable jaw at its heel is provided with the anti-friction roller F The end of the sleeve D, where contiguous to the knotter-jaws, is so shaped as to form a cam to open the pivoted knotter-jaw and to permit it to close as the roller on its pivoted jaw passes under the cam-shaped block G, mounted upon the end of the spring G, which is secured to the sleeve D at G The construction of theknotter and themechanism for opening and closing the jaw and the operation in tying the knot are well known and need not be. more minutely described.

Upon the stud B, I place the cord-holding disk H, (see Figs. 3 and (3,) which, as far as the construction and operation are concerned, differs little from some in common use; but in the matter of driving and retaining. in position it differs materially, as will now be ex plained. Cast as one piece with the disk is a pinion having six teeth, or any number that shall correspond with the number of notches in the periphery of the holding-disk, which teeth are beveled, so as to properly engage with a tooth or teeth of a bevel-segment. H are extensions of the teeth of this pinion, which extend from the body of the pin:

To this ion toward the axis of the cam and gear wheeltha't is, such is the general direction. As far as the extensions H of the teeth II are concerned, the pinion is in form a pin-wheel. The holdingdisk lI occupies such position relative to the knotter that the twine carried by the needle will, when laid across theknottier-jaws, be also laid into the proper notch in the disk. Coactin g with the notched disk is the holder plate or shoe 1, grooved to permit the disk to revolve therein, the edges of the metal forming the sides of the grooves being so curved and smoothed that the twine carried by the disk in its rotation shall not be treated harshly. The holder plate or shoe is pivoted at I to the sleeve D and is elastically held in contact with the disk by the spring 1 Referring to Fig. 1, the breast-plate is shown to have the slot E for the passage of the needle in its movement to lay the twine on the jaws of the knotter. At its lower end near the knotter the slot is extended laterally and given the peculiar form shown at E The purpose of this lateral extension of the slot will be fully described when describing the discharge of the knot from the knotter; but in this connection it is stated that provision must be made for keeping the twine, when laid across the jaws of the knotter as in Fig. 1, from escaping through the slot. Supported in the sleeve 13 is the short rockshaft J, to one end of which the tucker is firmly secured. To the opposite end of this shaft is secured the short arm J. The short arm is provided with an anti-friction roller J which moves in the cam-groove in the knotter operating wheel. (Shown in Fig. 7.) The tucker-arm so bent as to reach for a distance in a direction parallel with its axis of vibration, and is then bent so as to lie fiatwise beside the breast-plate, as seen in Figs. 7, 8, and 9. The position of the shaft of the tucker and its length are such that its operatingpoint J 4 shall move so close to the needle as it brings the twine around the gavel that it may take the same and depress it to a po sition within reach of the knotter-jaws, as shown in Fig. 11.

In Fig. 7 the needle is shown in section and the twine in relation thereto in that part of its movement in which it is when the point J" of the tucker sweeps in the path indicated by the broken lines to engage the twine. I provide the tucker-arm with the supplemental finger J in such a position that when the tucker is at rest the finger shall occupy the position shown in Fig. 10, where it, is seen to be thrust across the slot E" in the breastplate, and the twine is prevented from escaping the knotter. A third position is given the tucker for an instant-n am'ely, that shown in Fig. l.where it is thrown upward so fa'r'as to be fully withdrawn from crossing the slot, so that the knot stripping or discharging device may be at liberty to remove the completed knot by carrying the twines into the slot E".

K is an arm free to revolve on the studbolt 0, and adapted to rotate close to the breast-plate on a plane parallel thereto, and its extremity K of such length as to sweep by the end of the knotter between the latter and the breast-plate and to overreach the width of the slot E". This arm is preferably made of steel, and has as one piece with it the knife K its blade bent abruptly to a plane at or near a right angle to the arm K and of such length and radial sweep as to pass between the cord-holding disk and the knotter.

The operating parts have so far been treated but singly. The mechanism for giving them movement in the proper directions and at the proper relative intervals will next be considered, and the respective operations and the coaction of all of the elements of the invention explained.

As already stated, the stud-bolt C serves as means for connecting the breast-plate to the frame. which the segmental cam and gear wheel for giving the parts motion may revolve;

Referring now to Fig. 6, L is a sleeve free to revolve on the bolt 0, and having as one piece with it the following partsi L is a thin disk concentric for nearly its whole circumference, and its periphery adapted to slideon the delay-surface F on the knotter-pinion formed by cutting the flange of the latter to conform to the same. At the point where the periphery of the disk is cut away to permit the flange of the pinion to roll, and abutting against such space, are the teeth L of the segmental cam and gear wheel which operates the knotter, of such number,- radius, and pitch that they may engage with the teeth of the knotter-pinion and give the latter one rotation. At the ending thereof the completed part of the periphery again strikes beneath the delay-surface of the pinion and looks it.

Upon the side of the disk L nearest the breast-plate E, I arrange two flanges If and L, of proper width to form a cam-groove that shall permit the roller J to travel therein and give it properbreadth of tread. These flanges are, at all parts of the wheel,- parallel, and the contour of the channel formed by them such as shown in Fig. 7, where it is seen that for the greater part of the circumference (that part numbered 1) it is concentric, and hence during the greater part of the revolution of the wheel the tucker-finger moved thereby will remain in one of the three positions longer than any other. This position is that shown in Fig. 10, where, as already explained, the escape of the twine from the knotter is prevented by the finger J resting across the slot E".

In the movement of the binder the needle soon reaches a certain position and the tucker is required to engage the twine and carry it positively to the knotter by a downward sweep. To give the tucker this movement, I give the cam-track a sudden bend outward,

Besides this it serves as an axle on as at 111 so that as the inner wall impinges upon the roller the tucker will be thrown to the position shown in Fig. 7. The tucker should The operation of the knotter in forming the knot by a rotation on its axis is precisely like that well understood, and neednot be further described, other than to speak of the positions of the strands of twine when the tucker withdraws and the stripping-arm K approaches. \Vhen the knotter comes to rest, the loop of the knot encircles the transverse jaws, and the strands of twine that are to form the bow are held between them and ready for the completion of the knot by the forcing of the loop over the bow and off the jaws by stress in the proper direction applied to the band-twine. The incline 2% in the cam and gear wheel now effects the removal of the tucker to the position shown in Fig. 1. The twine-cutting and knot-discharging arm, as stated, revolves on the stud-bolt O as an axis, and, from preferen ce, I make them as one piece with the sleeve L,- providing the latter with the wing L and riveting the arm thereto. The arm is so located and its radial sweep is such that at the instant that the knotter has done its work and the tucker has withdrawn from across the slot E4 the edge of the arm K cuts across the axis of the knotter between the latter and the breast-plate, engaging the twine and suddenly changing its direction to such a vposition in relation to the knotter that the stress on the twine incident to the expansion of the bundle shall be effectual in same time completing it by drawing the loop over the bow.

Referring to Fig. 7 it is seen that the blade K of the knife is somewhat in advance of the stripping-arm K; hence, of course, the twines drawn between the holder and knotter will be severed just before the knot is free from the knot-ter. After the completion of the operation of discharging the knot the tucker may be brought to its position for stopping the new twine laid across the jaws of the knotter from escaping into the slot E. For this purpose I give the cam-track the outward throw 8%, which, acting upon the short arm J, rocks the tucker to the position shown in Fig. 10.

During the interval of time occupied in tying the knot and discharging the same another operation has been performed, which will next be considered. On the face of the wing L in proper position to engage the teeth of the cord-holder pinion H is a single tooth L, properly beveled and adapted to engage the teeth of the pinion and thus move the holding-disk. I use a single tooth, and hence advance the pinion but one tooth at a time, and, the number of notches in the disk corresponding with that of the teeth at each passage of said single tooth, a new notch isgpre sented to receive the twine. 1

All of the movements have now been described, and it is seen that such movements have been made by parts combined as one piece, the proper timing of the movements being due to proper radial arrangements 'of the cam, segment, and other parts. means for locking the pinlon in any position to which it may be advanced by the single toothed segment, I provide a flange M on the sleeve L in such a position that it 'ness that its periphery shall move, close fit-' ting, between the extensions 11 of the teeth sitions shown in Fig. 2 no movement of the pinion can take place. To permit rotation of It is clear that with the parts in the po- I the holder at the proper interval, the disk or flange M is cut away, as seen in Fig. 7, to form a notch of width slightly greater than the diameter of the circle described by the rotation of the extensions H of the pinion. The tooth L is so placed that at the time the twine is fully laid into the notch of the holder the said tooth shall engage a tooth ofthe pinion. At the same instant the edge M of the flange M has passed beyond the space between the teeth and set the pinion free, which moves as long as the tooth L remains in contact; but

when the tooth has ceased to move the pinion, the latter having fully assumed its new position, the edge M of the flange passes in between a succeeding pair of the teeth H,

and the holding-disk is again locked.

By the use of the miter-gears A and L the former keyed to the shaft A and the latter cast upon the sleeve L, I am enabled to rotate the'mechanism that ives motion to the knotter, tucker, cutter, holder, and stripper 011 such a plane that the knotter may be driven by spur-segment and pinion rather than by bevels, and to vibrate the tucker on a plane at a right angle to the axis of the knotter, and to move the holder by the same rotating parts.
